300,000+ Prometheus Servers and Exporters Exposed to DoS Attacks

Security Threat

In this research, we uncovered several vulnerabilities and security flaws within the Prometheus ecosystem. These findings span across three major areas: information disclosure, denial-of-service (DoS), and code execution. We found that exposed Prometheus servers or exporters, often lacking proper authentication, allowed attackers to easily gather sensitive information, such as credentials and API keys.
